Protein data bank. Wwpdb data centers serve as deposition annotation and distribution sites of the pdb archive. Each site offers tools for searching visualizing and analyzing pdb data. This resource is powered by the protein data bank archive information about the 3d shapes of proteins nucleic acids and complex assemblies that helps students and researchers understand all aspects of biomedicine and agriculture from protein synthesis to health and disease.
Since 1971 the protein data bank archive pdb has served as the single repository of information about the 3d structures of proteins nucleic acids and complex assemblies. Download archive data download instructions every wednesday from 00 00 utc all new and modified data entries will be updated at each of the wwpdb ftp sites. The worldwide protein data bank.
Protein sequences are the fundamental determinants of biological structure and function. The worldwide pdb wwpdb organization manages the pdb archive and ensures that the pdb is freely and publicly available to the global community. The protein data bank pdb is a database for the three dimensional structural data of large biological molecules such as proteins and nucleic acids the data typically obtained by x ray crystallography nmr spectroscopy or increasingly cryo electron microscopy and submitted by biologists and biochemists from around the world are freely accessible on the internet via the websites of its.

The protein database is a collection of sequences from several sources including translations from annotated coding regions in genbank refseq and tpa as well as records from swissprot pir prf and pdb. The pdb ftp archive is quite large requiring over 1tb of storage and continues to grow with each weekly update.
The protein data bank pene file format is a textual file format describing the three dimensional structures of molecules held in the protein data bank the pdb format accordingly provides for description and annotation of protein and nucleic acid structures including atomic coordinates secondary structure assignments as well as atomic connectivity.
